IONM Exam Questions and Answers
Graded A+
patient safety - Correct answer-Why is it important to have EP equip. properly
grounded?
A clinical neurophysiologist is responsible for several ORs while a tech is available
in each room to place electrodes, setup equip., and monitor the case. - Correct
answer-What is the most common structure of an IOM team?
Before electrodes are connected to the machine, to avoid power surges to the
patient. - Correct answer-When is the best time to power on the IOM equipment?
Yes - Correct answer-Does the experience of the IOM personnel affect the rate of
post-op neurological deficits?
1 Interpret recordings and communicate findings to surgeons.
2 Troubleshoot equip problems.
3 Knowledge of anatomy and surgical procedure. - Correct answer-Responsibilites
of IOM personnel (3)

,Exam of brain activity patterns can provide valuable info., regarding integrity of
neural structures. - Correct answer-On what principles is IOM based?
Cost Effective
Early detection of ischemia and to assess the efficiency of surgical
countermeasures. Allowing for safer operations, avoiding neurological damage. -
Correct answer-What kind of benefits does IOM offer?
Total value of provided info. regarding functional integrity of the NS of a patient
anesthetized and not able to be neurologically examined. - Correct answer-Define
intra-operative monitoring.
The opposition of flow of alternating current (AC) - Correct answer-What does
impedance measure?
A salt bridge - Correct answer-Electrode impedance of less than 1k ohms may
indicate what?
Practical: No active pt participation is required.
Reliable: Normal recordings very stable over time.
Sensitive: Can promptly detect small changes in activity of the NS. - Correct
answer-Why is intraoperative monitoring valuable?
Spontaneous activity (EEG)

, Muscles (EMG) - Correct answer-Intraoperative monitoring employs recordings of
2 main categories of bioelectric signals: _____ and _____
1 Avert damage of neuronal structures that are at risk during certain surgical
maneuvers.
2 To identify specific neuronal structures and landmarks that can't be easliy
recognized on anatomical grounds only. - Correct answer-2 purposes of IOM
